Hi Group:

Well, the saga of my "new" Burke Millrite mill continues. You may remember
my post of my stupid mistake of raising the knee so high the elevating
screw slipped out of the knee "nut". I just wanted to clean the gibs.....

Bob May had some very good suggestions to loosen the knee gibs and let the
knee "drop" back into the nut. Good idea, except (as I found out) the nut
was so full of crud that the screw would not re-engage the threads.

What finally worked was to loosen the gibs per Bob, and jack up the knee
itself with a floor jack and 2x4 to raise the knee/elevating screw
COMPLETELY out of the nut.

I scraped/cleaned the crud out of the threads in the nut, added lots of way
oil, lowered the jack to drop the knee and viola... a working knee!!

I found tramming the head in X direction to be no problem.. Easy to adjust
by tapping the head. I have less than .0015 difference when rotating the
spindle left and right.

However, this is a fixed head unit and in the Y direction, I have .006
difference between the front and back.

I see no way to adjust the head front to back, so I am assuming I have to
adjust the knee gibs to get the table adjusted to the head. Yes??? or no?
After an hour of adjusting the knee gibs, I am still no closer than .006
front/back. So, maybe adusting the knee gibs is NOT the way to go.

I am using a .0005 indiator mounted in a 3/4 rod/collet swinging a radius of
about 5". I am swinging the indicator over a set of matched 123 blocks to
avoid running the indicator over the table slots.

Thanks for any ideas.
